WILLIAM NEVINS COOK, OF NEW YORK,Y N. Y., ASSIGNOR TO E. B. MEYROWITZ, INC., A COREORATION OF NEW YORK.

GOGGLE NOSE BRIDGE.

My invention relates to goggle construotions and particularly to adjustable nosepieces therefor. l

Goggles are of vital importance in the operation of high speed transportation, such as aeroplanes, dirigibles, racing automobiles, etc., since it has been found essential that the operators eyes be very carefully protected against the wind stream caused by rapid passage through the air, and from flying small objects which may be encountered in the air. This protection is most conveniently provided by means of goggles having glass lenses, worn over the operators eyes. It has been found essential, at very high speeds, such as those attained by modern aeroplanes, that an accurate, tight, comfortable, seal be made between the wearers face and the goggle frames. This seal is advantageously provided by the cushion construction disclosed in my co-pending applications, Serial No. @7,1655 tiled November l, 1924, and Serial No. 146,315, tiled November 5, 1926, whieh'disclose an advantageous pattern of sponge rubber cushion, adapted to attachment to the goggle frame, which is of different sectional size at differentportions of the periphery. The larger section is adapted to tit into the hollows of the weare-rs face, as, for instance, alongside his nose, where it is otherwise difcult to obtain a tight air seal, while the thinner portions form a seal between the frame and other portions of the face. This construction, as disclosed in the specifications, has been found particularly advantageous for the pilots of modern high speed aeroplanes. It has been found, however, that different users have noses of different widths, andV that, therefore, the hollows into which the cushions are fitted are separated by different distances and that accordingly a pair Yof goggles with a rigid nosepiece will not provide the best possible tit for all wearers.

My invention provides a particularly advantageous adjustable nose-bridge for a goggle construction, which is particularly adapted to the adjustment of the separation of the respective goggle lens pieces and their attached cushions, to fit the cushions most tightly to the wearers face. My adjustable nose-piece is particularly adapted to ready adjustment thereof, is particularly rigid rugged and durable.

when so adjusted, is adjustable under diiiicult conditions, as when in the air, and is particularly rugged and durable. It further provides a nose-bridge which is stiff, and free from lost motion when set in a given adjustment, and which is also free from rotational niovementduring the process of adjustmcnt.

The construction of my invention further provides hinge members between the goggle frames and the nose-bridge. This hinge construction allows the adjustment of the angle between the respective goggle frames to tit the facial angles of the wearer so that the goggles malte a close fit on'a face of the round, chubby, type, and an equally good tit upon a face of the .so-called hatchet type, the first requiring only a very slight-angle between the respective goggle frames and the second requiring a substantial angle. This feature further aids in the accurate iitting of the cushions to the wearers face. It is also convenient in that it allows of a folding of the goggles into a smaller and more compactl package, which is more conveniently carried when the goggles are not in use.

By this means I Vam enabled to construct goggles which are particularly adapted to severe service, which are readily adjustable to the needs of various users, and which are Other objects and structural details of my invention will be apparent from the following description when read in connection with the accompanying drawings, wherein:

Fig. l is a view in elevation of the face side of a pair of goggles showing cushions vand the nose-bridge of my invention;

Fig. 2 is 'a plan view of the same embodiment showing the upper side of the goggles and nose-bridge;

F ig. 3 is a front view of the same embodiment showing the nose-bridge construction in section;

` Fig. l is a view in horizontal section of the same embodiment of my adjustable nosebridge, and

Fig. 5 is a side view of the respective parts of the same embodiment, in position for assembly.

Referring to the figures, the usual goggle lframes l are provided and cushions 2 attached thereto. The usual head strap 4 with suitable adjusting means is likewise provided. The respective lens trames 1 are connected by a nose-piece 5.

Referring to Figs. 2, 3, 4 and 5, the nosebridge provides a pair ot upright members 6 and 7 which are rotatably mounted on a vertical axis in hinge members 8 and 9, which are in turn attached to the trames 1, which may desirably be b y riveting, or by other convenient means. Or, alternatively, the hinge members 8 and 9 may be made as integra-l part-s with the trames 1. rEhe upright members 6 and Y arelitted at the lower ends v16 and 17 to the hinge members 8 and 9, pass through the tubes formed in the hinge members, and are held in place by any con` venient means such as by riveting the ends over washers 10 and 11.

One ot the upright members, 6, ot the bricge-piece 5 is equipped with a holder, or clamping member, which has a soclrct 'formed Within a pair of jaws or lingers 12 and 14, threaded and having tapered ends. The other upright member, 7, may be 'termed into a cooperating `bar or bit 15, adapted to be held by a friction grip in said holder or socket. The member 6 is bent at a point near the middle, to bring the holder member into a horizontal position. The other upright member .7 is likewise bent at a sirnilar point near the middle to bring its upper end 15 also into a horizontal position. The member 15 is thus adapt-cd to enter between the jaws 12 and 14, and when so entered, the lower ends 16 and 17 of the upright members 6 and 7 are positioned relatively parallel.

The end ot the horizontal portion 15 may desirably be drilled and a key 18 inserted therein. The key 18 is adapted to enter the slotbetween the jaws 12 and 14, and to aid in maintaining the parallelism and positioning ot the uprights 6 and 7, and to prevent twisting between the respective goggle lenses.

A errule 19 is provided, knurled on the outside, with an internal thread matching the threads upon the jaws 12 and 14, and with a contracting cone 2O at one end, adapted to cooperate with the tapered ends of the jaws 12 and 14 to close them together, and thereby to grip the portion 15 ot the upright member 7.

The various portions ot my device may be assembled in any convenient order, except that it is desirable that the ferrule 19 be passed over the member 15 before the key 18 is inserted in the hole. It is desirable that the key 18 be ot such length that it will justV pass within the thread portion ot the terrule 19, but will not pass through the constricting cone portion 2O thereof. rEhis construction prevents the complete disassembly of the nose-piece without removal of the terrule 19 bv complete unscrewing from the threads yeach other,

on the jaws 12 and 14, thereby preventing accidental separation of the respective portions or' the goggle.

`This construction is particularly advantageous tor adjustment under difficult conditions. lt may haopen that an aviator adjusz-ts his goggles to his ,tace under conditions which he thinks are satisfactory, such as those which exist on the ground. He may then ascend for a flight and tind ait-ter the flight is begun, that the conditions have changed, which may be a change in temperature or in wind pressure or other teatures, so that the adjustment which seemed proper on the ground, no longer holds goggles and their cushions in the most advantageous position. The construction ot my invention is adapted to readjustment under such changed conditions, and it is readily possible for the avi atoi` to readjust the goggles with one hand, which he may do by loosening the terrule slightly and squeezing the uprights together or apart according to the needs and then retightening the terrule. rlhis has been found to be impossible with any other type ot' nose-piece construction without serious hazard to the aviator since all other constructions require for adjustment, the use ot two hands, or require the removal ot the goggles i'rom tie tace, as distinguished trom this construction which may be adjusted in situ, by one hand, and in spite ot substantial wi d ressnre. 'W hen so adjusted and the terrule tightened, the construction is then lirm and solid.

By the construction of my invention l have provided a goggle nose-piece which isy readily adjustable, which cannot be accidentally disassembled, which may be adjusted under difficulties, which when adjusted is rm and rigid, andwvhich is rugged and durable..

lVhile l have shown but a single embodiment of my invention in the accompanying description, itis capable of various modili-Y cations therefrom without departing from the spirit thereot, and it is desired, there- 'ore,y that only such limitations shall be imposed thereon a-s are required by the prior art or indicated by the appended claims.
